Maybe a hook or a nail? LOL! I would build a smaller box if i had time or extra space. It's simpler.Shop Made 2'x4' Down Draft Table
DOWNDRAFT TABLE BUILD - 2016
This is a project I needed to do to work on my boxes. I'm sharing details for LJ's who might want to build their own if they haven't already.
Minnesota winter means enclosed shop. Dust! I needed a table that would fill a number of functions for me. I wanted a large enough space to sand furniture parts as well as making boxes. I'm providing this blog for those of you who want to make a slightly larger down draft table/box. I have a 1 1/2 hp delta dust collector with 4 inch flex tubing running from my Garden shed into my shop. The 4 inch tubing and corrugated flex hose reduces the air flow. I also built a 50 gallon Thein chip collector and that all reduces the suction. I found a way around it for now while making boxes. I use plywood to cover half of the top increasing the suction.
I added 3/4 holes to the pegboard to increase the air flow. A Stympy Nubbs idea when he wasn't using Rockler parts. He built both types and you can check him out. Otherwise I have laid out my steps using my "some day I'm gonna use this" materials.
Kiefer posted a hood to go over his down draft table which I will aapt later when I have to close the shop again to Minnesota winter and kick up the heat and dust! LOL!

I drilled 140 three-quarter inch holes into a 2' x 4' pegboard. These were drilled with a three-quarter inch hole saw. Due to its coarseness in cutting and the softness of the pegboard there was some tear out on the backside.

After I treated the pegboard with a coat of Seal Coat. I proceeded to use my oscillating sander I proceeded to sand down the tear out on the back of the pegboard.

Assembled the frame from materials that I culled from the construction materials in my shop that were not cupped, warped, twisted. I used a lap joint with glue and pin nailer. I haven't made any corner braces so I used square 2×4 blocking for clamping and holding the frame square.

I had cut dado slots to the width/thickness of the pegboard. And I had to trim the pegboard that the slots.

The bottom of the 2×4' box has a half inch rabbit joint to accommodate a half-inch thick 2×4' piece of MDF. The rubber mallet that's a persuader.

Again, I used available materials from my shop to make a V-shaped vortex. This table is designed by available materials versus a materials list to the design of table. The rails are glued and screwed. But tacked first with a pin nailer.

This is is a set of rails notched into the frame to support the thin pegboard as the dado grooves were not sufficient.

I was able to purchase an inexpensive 4 inch exhaust port for about four bucks on Amazon. The holes were cut with a hole saw slightly smaller in the center approximately 3 1/2 inches high and two side holes with another hole saw approximately three-quarter inches in diameter. This provided enough air volume to meet the dimensions of the exhaust port.

I painted the pegboard with an exterior grade tinted primer which I had in my shop and added some resistance from the top. The pictures show the pegboard slide in over the rails noted above.

mixing my own wood filler from yellow, glue and the sawdust from the wood to fix the punky holes in the front of the table before painting.

Painted the complete frame/box with exterior grade white ceiling primer.
: Assembled/painted components of the downdraft table.

Attached the exhaust port and sealed with caulking.

Purchased some three-quarter inch rubber square feet at a good price from Amazon.com that I attached with three-quarter inch wood screws.

Did a test run with a porous rubber sanding mat purchased from Amazon which sits perfectly on top of my woodworkers bench. It works! LOL!
As always comments and suggestions are welcome and thanks for checking it out!
